You are insulting instead of answering the question posed to you - as usual. The question was how many were there 65 million years ago and how many after. You can not answer the question and neither can those who make that claim. What that means is that the claim is absolute garbage.
In addition, to back up my statement I pointed out the numerous classifications of animals which have survived through the 65 million year 'barrier' that the evolutionists claim existed WITHOUT ANY EVIDENCE. Of course they say this happened because they cannot give any trace of mammalian evolution, in other words 'the dog ate the homework' excuse usually given by evolutionists.
Fact remains therefore that my statement is correct. The only major classification of animals that went totally extinct at that time is dinosaurs and any explanation the pseudo-scientists of evolution want to make up has to deal with that fact.
